Abstract

A method and a device for measuring the flow rate of flowing, in particular liquid media using the Coriolis measurement principle, in which a measuring tube flowed through by the medium can be set vibrating and the deflection of the measuring tube is measured at at least two different measuring points via sensors and the flow rate can be determined from the amplitude and further vibration parameters with the aid of an electric evaluation unit. In this case, a further sensor is arranged at the site of vibration generation and the two other sensors are placed at sites which are arranged symmetrically with regard to their distance, referred to the tube section of the measuring tube, from the site of vibration generation. The evaluation unit contains logic means which, in the event of failure of one of the sensors, on the one hand report this, and on the other hand simulate the defective sensor in terms of evaluation by interpolation until the defective sensor is replaced.
